SPECIFIQATIGN forming part of Letters Patent Ii'o. 410,784, dated September 10, 1889. 7 Application filed December 31. 1883. Serial No. 295,006. (No model.)

To all; whom it may concern:

Be It known that L' JOHN COLVILLE, of

Brunswick, in the county of Glynn and State of Georgia, have invented certain new andv useful Improvements in Boring and Gross- Cutting Machines, of which the following is a full, clear, and exact description.

My invention relates toa machine for boring or drilling and cross-cutting, and has for its object to provide a machine of simple and durable construction capable of receiving a number of slats and automatically delivering the same to a a. sericsof saws;

' A further object of the inve11tion'is topro vide a machine for treating the slats used in the construction of acrate patented to myself on the 30thfday of March, 1886,- No.

The. inyentiontconsists in thenovel constructionand combination of -the several parts, as will be hereinafter fully set forth, and pointed out in-the claims. .i

. Reference .is to be-had to the accom anying drawings, forminga part of this specification, in which similar letters and figures offre'ferenceindicate corresponding partsin an. the views. 1

Figurel is a perspective view'ofthe m chine. Fig. 2 is a plan view of the same. Figs. 3 and 4 are side elevations. Fig. 5 is a side elevation of the bit-stock, the same being partially in section. Fig; dis a side B18V3z1 m of he ratchet-disk. Fi 7 i of the g-asaaacnmest.

to the shaft. Fig. 8' is a perspectiue'idetail View of a section of the carrying chaim'aiid Fig. 9 1s a side elevation of the machine-inns trating the application theretoof *a modi fied form of carrier. N The body or frame of the machine is P ef erably made rectangular, consisting 'of: four cornenposts 10, connected at or near the base by a series of cross-bars 11 and at the top by a seriesof similar cross-bars 12. .Zi beam 13 is attached in any approved manner to each side of the body-frame at. the center of the same, which beams 13 are projected horizontally outward from the body, and are supported at their outer ends by suitable legs 14-, and the outerextreinifies of the said series of drills or hits and ide beams 13 are connected by a cross bar 15. 9

Upon the rear c0rner-posts of the body near the top a transverse driving-shaft 16 is journaled, provided with three or more pulleys 17, secured thereto within the bodyframe, a driving-pulley 18 at one outer end, and asecond driving-pulley 19 at tho opposite end, as best shown in Figs. 1, 2, and 4. ;The end of the shaft 16, carrying the pulley 19, is provided with pinion20, meshing with a spur-wheel 21, rigidly secured to a second transverse shaft 22, journaled upon the side beams 13 within the body-frame,

v slightly in advance of the driving-shaft l6, the two shafts '22 and'ld being parallel. j each extremity of the shaft 22 a crank-disk The spun.

23 and 24 is respectively secured. wheel 21 is attached to the shaft 22 contiguous to the crank-disk 23 and outside of the body-frame, asbest illustrated in Fig. 1. A second transverse shaft 25 is jonrnalcd within the body-frame upon the side beams 13, which shaft, Within the frame, is provided with'two rigidly-attached spaced chain pulleys of wheels 26, as best illustrated in Fig. 2. Upon oneouter extremity of the said ,.-shaft 25 a disk 27 is loosely mounted, pro- "vided with a diametrical slot 28. The disk 27 is connected with and is driven from the disk 23 on the shaft 22 by means of the pit man 29, pivoted at one end to said disk 23, the other end being adjnstably secured to the disk 27 bymeans of a bolt and 'loclr nut, the saidLbolt being made to pass through the slot 28 of thesaid disk, as bestillustrated in Figs.

Oneal? two ratchet-wheels 30 are keyed or lotiherwisesecured upon the shaft 25 adj acent to theinn'er face of the disk 27, as illustrated in Figlv 7 ,which ratchet-wheels are engaged by pawls 31 or dogs pivoted upon a stud 32, projected from the inner face of the dislnthe said dogs being held inconta'ct with. the said ratchetvwheels by the springs 33, having a bearing upon the upper face of the dogs which springs are --se'cnred to the posts 34, a1so projected from the inner face of the disk above and essentiaily parallel with the stud 32, as best iliustrated in Figs. 15 and 7.

,Another transverse shaftis jcnrnaled provided at one cross-bars ol' the body-frame, outer end with a drivingpulley 36 and a smaller pulley 37, adjacent to the drivingpulley, the latter pulley 37 being connected by a belt 38 with the pulley 19 upon the driving-shaft 16, as best shown in Figs. 1 and 2. By this means the lower shaft is driven directly from the main driving-sh aft. The shaft 35 is in turn adapted to drive a shaft 39, journaled upon the side beams 13 in front of. the. body-frame, asillustrated in Fig. 2, the same being effected by belting the pulley 36 to a pulley it) on the shaft 39. The shaft 39 is provided with a thread 40, produced thereon between the side beams 13, and the said shaft 39 is adapt ed to carry two or more saws il, clamped between. two collars t), which collars are adjustable upon the threaded surface of the shaft and held by suitable nuts.

At the forward end of the wing or bed of the machine formed by the supported side beams 13 a shaft i3 is journaled, carrying spaced chain wheels or pulleys ii, the spacing of the pulleys 4-4 upon the shaft 453 being made to correspond with the spacing of the similar pulleys 36 upon the shaft 25.

The wing or bed of the machine is preferably provided with a platform 4-5, elevated slightly above the side beams 18, which platform extends from. a point adjacent to and to the rear of the forward chain pulleys or wheels ll close to the body of the machine and over the saw'shaft 39.

Endless chain belts A6 are made to pass over the aligning chain-pulleys ii and :26, the said chains being adapted to travel above and be. low the platform 45, being guided in their travel by guide-strips i7, attached to and extending longitut'linally of the platform 45, as best illustrated in Fig. 1, the guidestrip to the right being adapted to engage with the inner face of the endless chain 16 at the right, and the guide-strip at the left being so located as to be in contact with the outer surface of the leftrhand endless chain. The endless chain belts or carriers 46 consist of a series of pivotally united solid links 48, as best shown in Fig. 8, so constructed that a single link a will alternate with two parallel spaced links 11, the extremities ofthe single links being held between the spaced or parallel links by a suitable pivot c. A finger 49 is attached to each pivot c at the outer end, which fingers are adapted to project rigidly upward beyond the links, as shown in Fig. 8. In the completed chain or carrier the several fingers are located upon the outerside. These fingers 49 are adapted to retain and space the slats 59 to be treated horizontally across the table or platform of the wing or extension of the machine, as best illustrated in Fig. 1, the said strips or slats being fed to the carrier by means of a chute 51, located at the front of the machine innnediately above the shaft 43, as best shown in. Fig. 3, the said chute being of a width to just acconunodate the slats,

upon the lower .which slats are laid horizontally upon the bottom of the chute, one bearing; against the other as the carrier or chain is revolved, and as the several pins rise upon the chain-wheel 6 a slat automatically drops into the spaces between the fingers by reason of the chute having an upward inclination. The slats are thus carried automatically over the platform tothe main frame of the machine, to be treated in a manner to be hereinafter set forth.

The slats are prevented from lmckling, up or rising; from their proper position by means of a guide-arm 553, located ad jaeent to the main frame and projected transversely above the platform 4:5, the ends of which guide are supported upon suitable standards rigidly attached to the outer face of the side beams 13. Auxiliary guidearms 5i. are provided, extendinglongitudinally above the platform, the rear ends of which longitudinal guidearms are secured to the main frame of the machine in any suitable manner, the forward ends being attached to the transverse guide arm 52, as fully illustrated in Fig. 1.

Upon the upper portion of the main frame at the front a rock-shaft is journaled in any approved manner, the said rock-shaft having attached at one extremity an upwardly and rearwardly extending slotted lever-arm 56, which lever-arm 56 at its upper end is adjustably connected with the crankdisk :12 on the shaft 22 by means of the link or pitman 57, as best illustrated in Fig. 4,

Upon the rock-shaft any desired number of sleeves 58 are secured, preferably by means of a set-screw, as illustrated in Fig. 1. Eachv sleeve is provided with a forwardly-extending horizontal arm 59, the outer end of which. arm is bifurcated to receive a clamp and a bitstock, as illustrated in Figs. 1 and 5. The bit-stock consists of a cylindrical body 60, provided with a longitudinal groove 61, and a head or chuck 62 at the lower extremity, adapted to receive a drill or anger 63. The body of the bit-stock is journaled in suitable bearings 64, secured on the front upper crossbar of the main frame, and similar cross-bars intermediate of the side beams 13 and the upper portion of the body of the main frame. The body 60 of the bit-stock is free to revolve and have vertical play in the bearings 6 4i, and each bit-stock is provided with a pulley 65, which pulley is sliddown over the body 60 and provided with an interior longitudinal feather 66, adapted to enter the groove 61 of the said body, as bestillustrated in Fi 5. By reason of this construction the'pulleys 65, being loosely keyed to the body of the his stock, do not interfere with the vertical move ment of the same. The several pulleys 65 are connected by belts 67 with the aligning pulleys 17, secured to the main drive-shaft 16, as illustrated in Figs. 1 and 2.

Each bit-stock is proyided at or near the upper end of the body with an attached peripherally-grooved sleeve 68, the groove in the said sleeve being adapted to receive the bifurcated extremity of an arm 59, projected fork between the tines is the widest.

', gage bars 69 move up and down with the bitstock, and are held at. all times in' a predetermined perpendicular posit-ion by means of angled blocks 70, attached to one of the crossbars of the mainframe and bearing upon the outer edge of the said gage-bars, as illustrated in Fig. 1. The. object of the gagebar is to retain the slat, when fed forward to be bored,

in such a position that the bit or anger will strike the upper surface of the slat at a central point between the sides. The employmentof the gage-bar is necessa'ryg-since the] slats fed to the drills oraugers may be more or less warped.

In operation the bit stocks are represented as'being fed downward, a slat having been fed, forward in positron to be bored, and-the said slat having been trimmed at the ends by the saws i]; priorto arriving beneath the bits. The'disks-23 and 24 are on their forward throw-whereupon the dogs 31 slide over the ratchet-wheels 30, thus permitting theshaft 25, carrying chain-wheels, to be idle.

The forward throw of the disk 24 elevates the lever-arm 56', rocksthe shaft and depresses the shaft arms 59, which arms carry the bibstocks downward. As the movement of the shaft 55 is gradual, the'bits are ,also gradually fed into the slats, the said bits be-' ing meanwhile rotated by the connection of the bit-stocks with the main drive-shaft 16.

the shaft 25.

As the disks 23 and 24, which move together, are on their rearward throw, the disk 24 raises the-bit-stocks and the .disk 23, acting upon the disk 27, causes the dogs 31 to engage with the ratchet-wheels .30 and revolve This sets the endless chains or carriers in-m'otion, and a slat is brought forward to replace the finished slat, which is dropped down'to the ground. Just as the slat reaches the proper position beneath thebits the disk 24 commences its forward throw, and likewise the disk 23, whereupon the move ment of the shaft 25 is stopped, the rotation of the carrier or endless chain ceases, the bits are again fed downward, and the. forked ends of thegage-bars, which project below the bits, are made to span and embrace the slat just fed forward to be'bored, and retain said slat in ajixed position in proper alignment with the bits, and as the bit-stocks are fed farther downward the bits are made toenter the slat '72 are secured,

rier. The chain. belts and the shafts carrying the chain-wheels are-dispensed with,and a shaft '71 is journaled upon the front cornerposts of the main frame near its base, upon which shaft a series of large toothed wheels shaft 55 is manipulated by the link or pitman connection withrthe disk The platform of the extension of the main frame is provided witha' series of spaced longitudinal slats, between which slats the toothed wheels '72 revolve and the chute 51 is mounted upon the platform and made to 7 In Fig. 9 I illustrate a modified form of car- The shaft is intermittently project atan inclination downward to deliver the slats to the wheels 72 as they revolve, which wheels, as theyreceivo the slats between the teeth, carry the same upward to the bits, and-when a slat is brought in, position immediately beneath the hits, as shown in'Fig. 9, the wheels 72 cease to revolve, and the bit-stocks are carried downward and the bits permitted to enter the slat.

The. intermittent movement of the carrier ofihe bitstocksin the -m0dification illustrated in Fig. 9 is identical with the movement ofthe similar parts in the preferred form of machine illustrated in Fig. 1.

I desire it to be distinctly understood that while I have shown'and described specific constructions, other equivalent construction may beemployedwithout departing from the spirit of the invention.

Having thus'described my invention,what I claimas new, and desire tosecure by Letters Patent,is;

-1. The combination, with a-fe'ed mechanism, of a series of bit-stocks, a rock-shaft car.-
